*Newbie* Can't turn on PC...

"Have you checked that the CPU HEATSINK is still on the CPU?"

CPU HEATSINK?
What is that?
I'm doing my best to learn as much as I can about computers, but I'm always learning new things.

You need to learn about http://www.google.com

Let's try...

What is a cpu heatsink? at said site. Yes, that covers it. As such, I feel no need to duplicate such stellar content here.

Bob

I'll have to look into that.
But the fans start to run then stop.
Maybe the fans are causing the problem?
Could that be it? Do I need to replace cooling system?
One of my friends thought it might be RAM related, is that a possiblity?

It's becoming clear that you don't want to do the research. Let me offer this. Many systems now do exactly as you write to save the CPU from damage when the heatsink has come off.

Why not look?

Bob

Its not that I don't want to do the reseach, I just don't know what I'm looking for.

I supplied the words to type into Google and read the articles. I found pictures that show what such are and how to install such.

If you don't read such articles then your next stop is the repair shop.

What more can I offer?

Bob

Ok thanks for the help.
I already have one installed, so I'll just look to see if I need a new one.
I did open it up and found that it was loaded with dust, so I cleaned it out.

Thanks for the help.

Did this correct the issue?

Systems that start then shut down are generally related to heat and the first thing to check for. From their the possibilites to correct are endless.

If you would like to get a feel for whats involved for a system to boot see:

No so far it has not fixed the problem. But I'm doing some research on the Cooling System.

I am reading the link you gave. Pretty interesting stuff I didn't know. Thanks.

A detailed list of hardware could reveal what's possible. CPU type, power supply rating and more.

Bob

I got a little fed up with the computer, so I took a break for a while. Well when I came back (about 3 hours later) I hit the on button and BAM! It worked!
So now the tower is running, but I have nothing on the monitor. The monitor just sits there like it's on standby or something, with the little yellow light just flashing and not turning green.
Could this be related to the motherboard?

I'm getting a list from my dad, once I get it I will post it asap!
